AAM 11.5" AXLE ASSY ''09-''11 CHY R

The Zumbrota Drivetrain RAA435-198A Rear Axle Assembly is a rebuilt AAM 11.5" axle designed for Dodge Ram 3500 DRW RWD models from 2009-2011, featuring a 3.42 gear ratio and open differential with posi traction. Each assembly undergoes a rigorous inspection process for straightness, cracks, and wear, with all internal components, bearings, and seals replaced. Gears are inspected for optimal tooth contact patterns, correct rolling torque, and precise backlash for proper lubrication and quiet operation. The axle tubes are inspected to ensure OEM straightness. Zumbrota's exclusive hydro-blast rinse and sandblasting, followed by a proprietary shot-enticed deep cleaning, ensure high quality remanufacturing.
